Definitions
- Spool valve or rotary valve 56 in circuit with channel 54 and operated (rotated) by link mechanism 57, controls the charging of reservoir 58 of the shooting pot or injection cylinder 59 equipped with an injection piston or charging piston 61.
- the spool valve 56 is formed with a transverse throughbore 62 and is shown in FIG. 2 in the closed position.
- the reservoir 58 communicates with channel 63 which leads to the nozzle assembly indicated generally by the reference numeral 64.
- Heating elements 52--52 maintain the desired processing temperature of channel 63.
- a manifold segment 65 secured to manifold block 51 is heated by elements 66--66 to maintain optimum temperature (400° to 440° F.) in the hot runner connecting extruder B (not shown in FIG. 2) to channel 67 leading to the reservoir 68 of a second shooting pot 69 equipped with an injection or charging piston 71.
